Embodiment 1

[0046] See figure 1 , figure 1 A schematic flow diagram of a method for implementing a routing protocol for a highly dynamic UAV ad hoc network provided by an embodiment of the present invention; a routing protocol for a highly dynamic UAV ad hoc network, comprising the following steps:

[0047] Step (a): Obtain the source node, several intermediate nodes and destination nodes respectively.

[0048]AODV is an on-demand routing protocol based on distance vector. It establishes and maintains routes according to business requirements, and establishes routes to destination nodes through flooding. It uses three basic control messages: route request (Route Requests, RREQ), route replies (Route Replies, RREP) and route errors (Route Errors, RERR), these three messages use port 654 on UDP, and use standard IP headers for processing. When broadcasting, the purpose of use The node address is a limited broadcast address. The broadcast frame uses the TTL field of the IP header to determ...

Embodiment 2

[0140] On the basis of the above-mentioned embodiments, this embodiment describes in detail another routing protocol for the highly dynamic UAV ad hoc network.

[0141] See Figure 4 , Figure 4 It is a schematic flowchart of another implementation method for a highly dynamic UAV ad hoc network routing protocol provided by an embodiment of the present invention. A routing protocol for highly dynamic unmanned aerial vehicle ad hoc network, comprising the following steps:

[0142] Step (S01): Determine whether the current node is a source node.

[0143] Step (S02): If the current node is the source node, then judge whether there is routing information to the destination node in the routing table, if exist, then send the data packet; if not exist, then generate and send the RREQ message, then judge whether to receive If the RREP message is replied to the destination node, if the RREP message is received, the destination node information in the RREP message is added to the loca...

Abstract

The invention relates to an implementation method and system for a high-dynamic unmanned aerial vehicle ad hoc network routing protocol. The routing protocol comprises the following steps of respectively acquiring a source node, a plurality of intermediate nodes and a destination node; generating a first RREQ message according to the source node; enabling the intermediate node to receive and process the first RREQ message, and update the first RREQ message to obtain a second RREQ message; enabling the destination node to receive and process the second RREQ message to generate an RREP message;and enabling the source node to receive the RREP message and add the information of the destination node into a local routing table. The routing protocol evaluates the life cycle of a path in a routediscovery process by taking the remaining time of a link and the remaining time of a route as the standard, the stability of the route discovery path can be improved, and the turn-off frequency of thepath is reduced to a certain extent in the high-dynamic topology change, and thus delay and expenditure brought by the re-starting route discovery process are reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method and a system for implementing a routing protocol of a highly dynamic unmanned aerial vehicle ad hoc network. Background technique [0002] With its unique flexibility, convenience and high efficiency, wireless network has become a rapidly growing field of communication in recent years, and it is also one of the important development directions. Among them, the Ad Hoc network has the following characteristics. Each node in the network can move independently and randomly; the network has the ability to dynamically reconfigure the route when the topology changes; In the case of a node failure, it does not affect the communication of other nodes; the independent network nodes form a network by themselves and do not depend on fixed communication facilities. These excellent characteristics make it occupy an important place in the field of civil and ...
